Gigabyte has been around
since 1986 and has consistently delivered products of only the highest quality,
thus establishing a very strong brand for themselves. We have seen them enter
the server/workstation market with multiprocessor motherboards such as the 6BXDS,
we have benchmarked their graphics cards that have quickly become some of the
most wanted cards in their class such as the GA-660
Plus TNT2 Pro, and they were even on top of AMD's Athlon release with
one of the first Athlon motherboards, the GA-7IX.
We had nothing but high expectations from Gigabyte when we found out that they
would be one of the first with an i820 motherboard design ready to ship at the
release of the chipset.

We first took a look at
their i820 based GA-6CX last November when the i820 chipset was supposed to
launch, but after a delay in the chipset's release due to a bug, it was another
few weeks before we managed to get our hands on the shipping revision of the
6CX. After putting the shipping version of the 6CX through our usual set of
tests we are very glad to see that Gigabyte addressed some of the issues that
we noticed with the original 6CX.

The original 6CX, like most
original i820 motherboards, featured a design that boasted 3 RIMM slots. After
a design flaw was discovered involving i820 motherboards with 3 RIMM slots,
Gigabyte went back to the drawing boards to redesign the 6CX with support for
only 2 RIMM slots. Taking away that third RIMM slot allowed Gigabyte to conserve
on PCB space, which naturally helps to reduce the overall cost of the motherboard.

The standard configuration
of the 6CX features 5 PCI slots, the usual 1 AGP 4X slot, and 1 AMR slot. Note
the use of the word 'standard' in describing that configuration, simply because
it is an OEM option to add an ISA bridge and a single ISA slot to the design
that would be shared with the fifth PCI slot. Of the five PCI slots, only three
are always capable of accepting full length cards while the first two PCI slots
can only accept full length cards if the system fan connector and front panel
connectors are not being used.

The universal AGP connector
on the 6CX supports all AGP 1X, 2X and 4X compliant graphics cards because it
lacks the 1.5v and 3.3v notches present on AGP 4X and AGP 2X only slots. Gigabyte
outfitted the AGP connector with an AGP retention kit designed to help hold
the graphics card in place, a unique and useful consideration on the part of
Gigabyte.

Unlike the ASUS P3C-2000
and the Supermicro PIIISCA, two other i820 motherboards, the 6CX does not feature
an AGP Pro connector. Since we have yet to see many graphics cards take advantage
of the 48 additional power and ground pins provided for by the AGP Pro specification,
this feature, or lack thereof, doesn't penalize the 6CX.

The actual layout of the
6CX is one of the best that we have seen on an i820 motherboard. The ATX power
supply connector is placed in a fairly out of the way location right next to
the floppy drive connector on the motherboard. The front USB connector is placed
at the end of the motherboard closest to the front of the case, which makes
perfect sense, although you would be surprised at the number of motherboard
manufacturers that place it away from the front of the case. The only complaint
we had was the row of capacitors sitting between the memory banks and the Slot-1
connector which interfere with the installation of large heatsinks/fans on your
CPU.
